WO1999035398A1 - The crankshaft driven air compressor - Google Patents

Abstract

The Crankshaft Driven Air Compressor integrates the Operation of the Pistons (11, 12, 20) and intake (23, 17) and exhaust (24, 15) ports of the engine and air compressor to eliminate the number of valve assemblies (21) in an internal combustion engine. It utilizes an air compressor whose walls (22) have an exhaust port (24) at the side to create an air reservoir (27) at the end of the compressor. The crankshafts (26) of the internal combustion engine drive the rods (18) and pistons (20) of the air compressor. The pistons (12, 12) of the engine synchronize the intake (17) and exhaust (15) ports of the engine with the operation of the intake (23) and exhaust (24) ports of the air compressor.

"Engine for The Crankshaft Driven Air Compressor", Applicant:

William Ronald Yee, a citizen of the United States, (US), 2798

South Country Club Drive, #8, Warsaw, Indiana 46580-9039 BACKGROUND OF THE INVENTION:

Air compressors may be driven by electric or gas motors or

other fuel driven motors. They may utilize pistons, fans or turbines

of a variety of types. Air compressors are often attached to Internal

Combustion Reciprocating Piston Engines to enhance performance.

I have invented an air compressor that is an integral part of the

reciprocating piston engine. I have invented a piston air compressor

driven by the crankshaft of an internal combustion engine.

BRIEF SUMMARY OF THE INVENTION

The use of air compressor pistons driven by an engine's

crankshafts is the subject of this patent application.

The Crankshaft Driven Air Compressor may be used with any

internal combustion engine with reciprocating pistons driving a

crankshaft and the patent is intended to apply to all engines that it

might be attached to. It is the subject of the primary independent

claim.

The Crankshaft Driven Air Compressor may be used with

particular advantage with the Two Piston Per Cylinder Engine. The

use of the Crankshaft Driven Air Compressor with the Two Piston

Per Cylinder Engine also is the subject of the primary independent

claim. The use of an exhaust port(24) on the side allows an air

reservoir(27) in the end of the air compressor to function as a brake

on the pistons and rods to reduce stress on the engine parts. This is

the subject of two dependent claims:

a. The location of the exhaust port(24) at the side and

b. The air reservoir(27) at the end of the compressor.

The air reservoir(27) does function as an energy storage device to

conserve energy used in braking the pistons(20) and rods(28) that

reciprocate. The energy is returned to the pistons(20) and rods(28)

when the air expands after the pistons and rods are stopped. The side

port(24) and air reservoir(27) are dependent claims that enhance the

basic patent.

Although I do not believe that it is necessary to use valves, I

believe that valves(21) at the exhaust port(24) of the air compressor

will enhance the efficiency of the compressor. The valves(21 ) may be flap

valves or any other common valve, spring loaded, pressure driven,

gravity driven or by any other common means of driving the valve.

The third dependent claim is the use of valves(21) on the exhaust

ports of the air compressor.

The placement of the intake ports(23) and exhaust ports(24) of

the air compressor to coincide with the opening and closing of the

intake( 17) and exhaust( 15) ports of the engine eliminates the need for

valves. The geometry of the pistons and cylinders operate the engine

and compressor without valves that complicate current internal

combustion engines.

Place the air intake port(23) on the air compressor at the

location where it will be covered by the piston at the same time that the internal combustion engine piston(12) uncovers the exhaust

port(15) of the internal combustion engine. The placement of the

intake(23) and exhaust ports(24) are the subject of dependent claims.

The placement eliminates the need for valves and allows the pistons

to operate the device without valve assemblies at the intake port(23)

of the compressor and the intake port( 17) and exhaust port( 15) of the

engine.

The final dependent claim is the much larger displacement in

the air compressor as compared to the engine. The large volume of

air utilized allows for efficiency in eliminating exhausts and much

cleaner burning. The sixth dependent claim is the large volume of the

air compressor as compared to the internal combustion engine. This

allows for the cleanest burning of the fuel.

The Crank Shaft Driven Air Compressor is an air compressor

that is integrated with the reciprocal piston internal combustion

engine. The integration is achieved by attaching the pistons(20) of

the air compressor to the crankshaft(26) of the reciprocal piston

engine. The internal combustion of the internal combustion engine

drives pistons(l l, 12) that push rods(18) that drive the

crankshaft(26). The crankshaft(26) drives the machinery. Attaching

the pistons(20) of the air compressor to the crankshaft(26) allows the

crankshaft(26) to compress air to supercharge the engine.

Placing the intake(23)(17) and exhaust(24)(15) ports of the air

compressor and the engine symmetrically on either side of the crank

shafts allows the pistons(l l)(12)(20) to open and close the

ports(23)(15)(24) without using valve assemblies. The optimum location of the air intake port(23) of the air

compressor is at the location that allows the piston(20) to close it at

the same time as the piston(12) in the engine opens the engine

exhaust port( 15).

The optimum location of the air intake port(17) for the engine

is further from the center of the engine than the exhaust port(15).

This allows the exhaust port(15) to open before the air intake

port(17) of the engine opens. The exhaust port(15) relieves the

pressure of the exhaust gases before the air intake port opens(17).

This allows the air compressor to work more efficiently at lower

pressures.

The optimum location of the exhaust port(24) for the air

compressor is at the side and near enough to the end so that the air

intake port(17) of the engine opens before the piston(20) of the air

compressor passes past the exhaust port(24) of the air compressor.

The exhaust port(24) of the air compressor should be close enough to the end of the air compressor to allow sufficient time for the air

from the air compressor to flush out the engine before the exhaust

port(24) of the air compressor is closed.

The diameter and volume of the air compressor should be

substantially larger than the diameter and volume of the engine. This

will allow enough air to be compressed to completely flush out the

engine. Complete flushing of the exhaust gases after ignition will

permit cleaner and more efficient burning of the fuel.

Claims

1. I, William R. Yee, claim as the independent claim: A piston air

compressor driven by the crankshaft(26) of a piston internal

combustion engine.

2. I, William R. Yee, claim as the first dependent claim: The use

of an exhaust port(26) on the side of the air compressor rather

than the end to allow an air reservoir(27) in the end of the air

compressor.

3. I, William R. Yee, claim as the second dependent claim: The

use of an air reservoir(27) at the end of the compressor to

function as a brake on the piston and an energy storage device

to reverse the direction of the piston and accelerate the return

ofthe piston(20).

I, William R. Yee, claim as the third dependent claim: The use

of valves(21) at the exhaust port(24) of the air compressor

which will enhance the efficiency of the compressor. The

valves may be flap valves or any other common valve driven

by gravity, gas pressure, springs or any other common device.

5. I, William R. Yee, claim as the fourth dependent claim: The

placement of the intake port(23) of the air compressor where

the piston(20) may close it at the time that the piston(12) in

the engine opens the exhaust port(15) of the engine to

eliminate the need for valves at these ports.

6. I, William R. Yee claim as the fifth dependent claim: The

placement of the air intake port( 17) of the internal combustion

engine to be opened after the air intake port(23) of the air

compressor is closed to permit the pistons(20)(l 1) to operate

these ports(23)(17) without the use of valves. I, William R. Yee, claim as the sixth dependent claim: The

diameter and volume of the air compressor is much larger in

diameter and volume than the engine to maximize efficiency

of exhaust and combustion.
